Abstract: A catamaran type water craft having two tandem pairs of scissors-like folding mechanisms disposed between and pivotally connecting to the opposing upright surfaces of adjacent, juxtaposed hulls. The folding mechanisms comprise two pairs of overlapped cross-linked beams joined about central pivot joints. A pair of cross-linked overlapped forward bow beams can also be provided, arranged so as to rise at an increasing angle to the water craft as the water craft collapses. When the boat is collapsed, the cross-linked beams fold like closing scissors to bring the opposing hulls laterally together, and the bow beams are drawn together, allowing the catamaran to fold to a width that can be transported by a truck or placed in a marina docking slip with the mast in its upright position. A mast is located in the pivot structure of the forward pair of crossed overlapped links.
Abstract: This is a displacement vessel shown configured for STOVL aircraft operations, providing multiple, into the wind launch positions. Widely separated port and starboard hulls carry transverse decks; this wide separation eliminates heeling and allows the vessel to maneuver without rudders. Pairs of torque tube legs connect the hulls; these round tubes would twist to absorb otherwise destructive stresses produced from grounding of a single hull. Within the hulls are ballast tanks so the vessel can be submerged to a small waterplane, creating a very stable platform; or to a heeled and lowered position to discharge amphibious vehicles. Motor driven propellers provide the propulsion for very high speed, made possible by narrow hulls. Combined with active fins to minimize pitching, this vessel will provide a stable platform in most seaways.
Abstract: An apparatus is convertible between a pontoon, a camper, and a trailer. The apparatus includes a main frame with longitudinally-extending beams and transverse beams. A retractable wheel frame supporting a double pair of wheels is pivoted to the main frame and is configured to swingingly retract into a center area of the main frame. Side, front and rear pontoons are attached to the main frame, with the side pontoons being extendable laterally to provide increased width to the apparatus. A vertical upright beam is slidably attached to the main frame, and includes a bottom hitch and a top boom, both of which are moved by an actuator attached to the upright beam.
Abstract: The boat is essentially mono hulled in its appearance but has the capacity wherein the lower and outer sections of the hull can be hinged out of a concave recess under the main deck and behind the full bow of the boat. The front of the hinging sections are curved to a point and graduated longitudinally to allow a bowlike profile at any given point as the sections are swung upward and away from the core of the boat. When the hinging sections are semi extended a full twin hulled operation can be achieved and when further extended a true triple hulled operation can be achieved with essentially three “bows” cutting the water. When fully extended the walls of the hinging sections come up to horizontal and also provide the benefit of extra deck space.
Abstract: A outrigger apparatus for connecting a pontoon to a canoe and placing a platform therebetween. The outrigger apparatus includes a pontoon portion. A coupling means couples the pontoon portion to a canoe. The coupling means includes a pair of bars. Each of the bars is elongate, having a first end, and a second end. Each of the first ends of the bars is removably coupled to the top peripheral edge of the canoe. A pair of brackets removably couples the second ends of the bars to the pontoon portion. Each of the brackets is elongate, and each has a base portion and an arm portion. The base portions of the brackets are removably coupled to the pontoon portion. Each of the second ends of the bars is removably coupled to one of the brackets. A support portion supports the user. The support portion is a platform. The platform has a pair of opposing edges. Each of the opposing edges is rested on one of the bars.
Abstract: A watercraft allowing relative motion of its deck relative to its hull structure to increase passenger comfort. The deck is mounted to the hull structure in a manner which permits relative motion of the deck structure to the hull in at least two independent axes.
